No one attacked the ARCH network and it is not a security risk to stake your coins. Leaving any unencrypted wallet file on your computer is idiotic, if you lost your coins it is your own fault.
I have been staking my coins for over 6 months and my balance only goes up. Do you know why? My wallet is encrypted.
What is the relevance of those wallets that you linked? If they have 32,000 coins they can probably access CEO info.
First of all someone did attack the ARCH network by targeting computers that were running ARCH wallets for staking.
Secondly it would appear that staking is a security risk as it exposes the staking computer to attack by way of being on the network 24/7 and visible as a peer.
Thirdly you are justify theft of property is OK because if you are able to steal it it means the owner did not secure it well enough so therefore it is fair game. Hackers
Hackers please note that Cryptotrout is cool with you robbing him as it will be his fault that your 0 day compromised his security.
Those are the wallets that have the coins.
